Thomas Edison took around a year to create a practical and commercially viable incandescent light bulb. He conducted numerous experiments and trials before he successfully developed a long-lasting and efficient light bulb that could be mass-produced.
Albert Einstein did not invent the light bulb; that credit goes to Thomas Edison. Einstein, a theoretical physicist, is known for his work on the theory of relativity and his contributions to the field of physics, but not for inventing the light bulb.
Albert Einstein did not invent the light bulb; it was actually Thomas Edison who is credited with creating a commercially viable light bulb after numerous experiments. Edison's team conducted thousands of tests before successfully creating a long-lasting, practical light bulb.
It took Thomas Edison years of experimentation and trial and error to create a practical and commercially viable incandescent light bulb. He started working on it in the late 1870s and finally developed a long-lasting bulb in 1879.
It took him 10000 triesnearly 40,000 times he failed in inventing a light bulb.

About an hour non stop!

i think it takes about 10 seconds if you already have the light bulb in your hand.
it took Edison 15-17 years to make the light bulb
Only two, as long as the light bulb has a hole, large enough for them to enter!
None. You vill change zee light bulb. Ve haf vays to MAKE you change zee light bulb!
